Application filed October 8, 1909. .pSerial No. 521,766.

To all w/zom 4it may concern: l

lie it known that I, Josi-nii F. MoiiAN, a

citizen-of the United States,- residing at.,

Park Ridge, in the count)7 of Bergen and State of New Jersey, haveinvented certain new and useful Improvements in Can-Open ing Machines,of which thelfollowing is a specification.

This invention relates to iml'irove'ments in can opening machines andthe obiect of my A invention is to provide a simple, inexpensive.

and highly efficient device arranged'toxcut the head of a can atonestroke of a lever.

The mechanism for carrying ont my invention comprises a can holder, aknife carrier in which the knife 'is at. all times heldy and concealedso .as not to injui'e'tlie hands of a user adjusting a cantherebeneatli, means for adjusting the can, means for causing the knifeto penetrate thel can as -it' makes its cycle, and means for actuatingthe knife as the level' is moved in a vertical pla-ne. l

Yith the above and other objects in view my invention consists inthecombination, arrangement, and details of construction shown in the.accompanying drawings and then more particularlypointed out in 'theappended claims. Similar reference characters designate similar partsthroughout the respective views, whei'ein- Figure 1 isa side elevation`of my invention Fier. 2- is a cross-sectional view vof the knife.depressing mechanism t0 be described,

" shown in detail, Fig. is an exaggerated top planof'the can table, Fig.4 is a cross sectional view`of the table and adjusting means therefor,Fig. 5 is a fragmental detail view partly in section of the rotary screwfor actuating the can cutter, Fig. 6 is a fragmental detail view of: theknife depressing mechanism showing the knife depressed`to engage a can,Fig. 7 is a detail view inperspective of the screw cylinder and looseshaft engaged thereby and, Fig. S is a top plan view of the screwmechanism and frame therefor. .f l l YReference being made to thedrawings which are merely illustrative of my vinvention', 1 designates asuitable frame fastened to a suitable support, said frame formedwitlntlie `outwardly-extciidingarms 2. 3 and 4 respectively designed tosupport the parts of my device. Fulcruiiied upon a pivot 4 fixed uponthe arm 4 is a lever 18' having a handle 1S, said lever being movablyconnected to the vertical shaft 16 so as to rotatably lift and depressthe saine vvertically, by any suitable means, such as the radius link l?pivoted to lever 18and to a block 27 in which may swivel shaft 16.' Thearm 2 is formed lwith a bifurcatedportion 5, the free end of each offsetof which 'is formed with a sleeve through which passes a vertical screw6 upon which screws a hand wheel' 7 disposed between the offsets of thearm 5, the screw 6 being of suflioient length can holding table. Saidtable is composed ofa bottom or base 8 secured rigidly to the screw 6and moving therewith, and mounted' upon said base are theYopositely-arranged rack bars 9, and 10 witi which the p'awl members 11are arranged to have engagement, each pawl member being secured upon acam member 13" which cams are disposed at diametrically opposite pointsandare arranged to ride against studs 13 formed underneath dogs 12 andmounted `upon the rectangular lguiding blocks' 42 by any suitable meansThe dogs 12 are of arranged to slide over the top 44 of the table whichis spaced from and suitably secured to the fioor or base S by anysuitable means such as posts 45. The forward end of each dog is formedwith a can engaging part 46.

The cam members 13 carry their pawls at 'their ends, and areintegrallyor otherwise formed upon the' inwardly or horizontallydisposed iange 12 formed upon a ring 8 formed upon the base 8 upon whichthe flange 12 rests, said flange being held against displacement by thevtop 44 of the be seen that when lthe blocks 42 are disposed centrally ofsaid openings, the cam members the pawls carried by said cam memberswill engage said racks also. The cam surfaces are so formed that whenthe wheel handle 15 formed aroundthe ring 8 is revolved to move the camsthe st uds will simultaneously move toward or"froin the axis of thescrew 6.

to allow for the vertical adjustment of the.

- working in elongated openings 43 formed in alineinent upon the top ofthe table,saidv blocks being integial with said dogs arid-l held againstdisplacement in said openingsgreater width than said openings and areembracing in sliding relation the ring 47V table. Reference being had toFig. 3 it willk will engage the studs at central points and 11o il versehars 20 which at their ends are rig-l idlyeonnected hy the bolts Saidposts andhars form a. frame `which rests upon the cam head 3S and isheld rigidly in upright position, so that the 'pin 2i may at all timesfit the spiral grooves 25, by means or' the tie holt nearest the frame lwhich passes through the enlargement 49 formed upon arm which :sarranged to supymrt the horizon l cam head the usual nuts heiuginterposed so as. to properly position said tie holts.

'The channel 86 3 in member 37is formed with a reduced part tahle will ride against the dependingstuds 13,'

termimiting` in a relatively narrower part which is in registration witha vertical recess 33 .formed in member 34 into which the cutting surfaceoil the knife is held by means of the spring coiled around' said knife70 and hearing at one end against 'shoulder 53 and-at the other againstthe shoulders formed by the narrow opening in member 37. Springs areseeuredlto the ends of the dogs and to the top of the talolerespectively.

The can opener operates as follows;- By means of the screw Wheel 7 theuser will raise the can table until the eau is brought alongside of hutat a slight distance apartl from the knife carrier 34;. To mount a can80 in position upon the top 44 of the tahle the hand Wheel 15 will herevolved so as to advance the dogs i2 toward the center of thev Bymoving said wheel the cams 13 which forming'part of the blocks 42 willmove them in their rectangular Openings 43 thereby imparting motion tothe dogs 12 and causing them tomore forwardly or rearwardly. parvis 1iwill ride over the teeth of the rack hars 9, and 10. Y[t will heunderstood that any suitable means may ne employed to r lease the pa-wlsso as to retract the dogs in removing the can clamped thereby, no such Smeans being' shown in drawings, huiJ the provision of the means isWithin the prov,- ince ot' those skilled in the art.

The

lever will then lie-given a full stroke so that the topof cylinder 26will move alongside the bar24 and owing to thc configuration of' the camgrooves and theposition of the pm .24 the screw cylinder Will rotate asit moves and will complete one ,revolution. It will be seen that saidcylindeiI will move in telescoping relation Yagainst thepolysided'upright shaft al and owing to the channel of said cylinderbeing polysided saidv shaft will rotate in common with said cylinderwhich will .also make 'a completev revolution. As said shaft 5l rotatesthe knife carrierA \vill obey its movement and roller 3l operativelymounted thereupon will ride off the edge of the cam way Q9 onto theperiphery of the cam head 20, which head is stationary as aforesaid.iVhen this shall have been-done, the cutting edge ofthe knife Will havebeen caused to project through the openinor 33 in the knife carrier andWill penetrate Italle can and as said carrier completes its cycle ofrevolution, the knifewill cut the head of the can sufficiently to enableit to be bent back. "When the roller 3l is depressed as it engages thehead of thecalu .vay, the member 3l' will move in the socket 'member 37against the tension of the spring 35 thereby causing the knife 32 toadvance against the head of the can to be eut. lYhen the cutting shallhave been effected the lever 1 8 will move upwardly to its upper normalpo` siton and as it is being restored the knife carrier will move to'occupy its first-named position, the roller 3l falling -into the cam way29 and engaging `the edgethereof to lie adjacent the edge 30 of the camhead when the cylinder shall cease to rotate. This will have caused thespring to gradually recoil to lift the knife so as to hold it,out ofprojecting position. [t will.. he seen from the above construction thatthe operatorfcan .adjust the can against tbeknife carrier Without thehazard of injuring his fingers by means of' any projecting surface oftheknife since the-latter is held concealed at all times until the leveris actuated. lThe knife carrier may or may not be in engagement with the4can as .it rotates.

Numerous modifications may be resorted to in practice Without departingin .principle frmthe invention disclosed.
